Presented by Compax Corp., the total duration of the film clocks in at over two minutes and was filmed in color. A narrator tells the story, and in a spoof of the "Tom Swift" radio narrative style, provides interjections whenever a character speaks, i.e., "Said Shrinkel." The plot involves Shrinkel and his sister Stretchel, who have been lost for years in the woods only to come across a gingerbread house inhabited by a witch. Naturally, she instantly shoves them into an oven for dinner. But to her surprise, the two emerge unharmed as they reveal their true names: the "Pak-Nit RX Twins."

The product has a twin effect, as it prevents both shrinking and stretching to fabrics in the dryer. It would appear to the witch that our heroes are named simply as a front. The film concludes on a happy note, as the witch discovers that she too can benefit from shape control.
